22 years old and I can only hear to about 14 just barely, perhaps not anymore. The right ear doesn't even hear up to 10 khz. Around last fall after many noise injuries and the start of migraines, I could still hear 16-17 khz just barely in the left ear. That is surely gone now.
Damned firecracker. Damned Mad Max at the Imax. Damned migraines after Imax.
I used to have dog ears and heard all the way up to 22 khz just 5 years ago!
